Violet Fox writes: “In March 2025, I wrote about anticipatory obedience at the Library of Congress (LC), describing how LC fast tracked changes to the Library of Congress Subject Headings relating to the Gulf of Mexico and Mount Denali. When Trump issued an executive order on August 27 directing federal agencies to change Lake Ontario to Lake America, catalogers around the world waited to see how LC would handle the changes. On September 3, LC scheduled a proposal to change the subject heading, and on September 11, the change was approved. The speed with which this happened is astounding.”
